In this study, the nanoporous γ-alumina catalysts were prepared by the sol-gel method using hydrolysis of aluminum isopropoxide in the presence of TX-100 or gelatin/TX-100 mixture. Catalysts were characterized by XRD, FT-IR, TEM, BET-BJH and N2 adsorption-desorption isotherms. To investigate reactivity and selectivity of the synthesized catalysts, dehydration reaction of 2-octanol was carried o...

PCNP diphosphines, in conjunction with Cr(acac)3, are excellent ethylene oligomerisation catalysts high activity and selectivity towards both 1-hexene 1-octene formation.

Starting from 1,1'-diacetylferrocene the ortho-amino,α-dimethylamino[3]ferrocenophane system 3 was prepared. This was converted to the o-imino,α-Cp-derivative 6. Subsequent treatment with e.g. an excess of methyllithium followed by ZrCl(2)(NMe(2))(2)(thf)(2) and Me(2)SiCl(2) eventually gave the [3]ferrocenophane based Cp-amido zirconium complex 11b. In a similar way the [3]ferrocenophane derive...

Cavitand molecules having double bond terminated alkyl chains and different bridging groups at the upper rim have been grafted on H-terminated Si(100) surface via photochemical hydrosilylation of the double bonds. Pure and mixed monolayers have been obtained from mesitylene solutions of either pure cavitand or cavitand/1-octene mixtures. Angle resolved high-resolution X-ray photoelectron spectr...

From evidence obtained by nuclear magnetic resonance, mass and infrared spectrometry, and chemical techniques, these compounds were identified as cis-4-decene-1, lodioic, cis,cis-4,7-decadiene-1, IO-dioic, cis-4-octene-1,8dioic, glutaric, and adipic acids, N-isovalerylglycine, and N-(methylenecyclopropyl)acetylglycine.
